$64 Allwinner V3 Action Cameras Support 4K Video Recording (or Not?)

An “Allwinner V3 4K Ultra HD DV Sport Camera” just appeared in GeekBuying product feed which the company sells for $84.39, and searching for alternative sellers led me to Soocoo F60 4K action camera sold for $63.34 on GearBest. Both cameras look the same, and the price appears amazing cheap as 4K cameras such as GoPro Hero4 or Sony X1000V normally sell for $500 and more. But one of the tricks is that both “4K” camera are likely based on Sunchip 4K camera design, which does support 4K video recording, but only at 15 fps.

Battery – Detachable 900mAh battery good for about 90 minutes at 1080p30.

Power Supply (Charger) – 5V/1A

Dimensions – 5.9 x 4.1 x 2.9 cm

Weight – 58 grams with battery

Allwinner V3 Camera Accessories

The camera will ship with lots of accessories including a waterproof case, the Li-ion Battery, a charger, a USB cable, a user’s manual, and various mount options.

The WiFi connection can be used to transfer images and videos, for remote control function, to sync and share albums and manage the settings, and the company recommends to use Youmera or FinalCam apps to use with WiFi. Other use cases for the camera include car DVR and PC camera.

To answer the question in the title, whil the camera technically supports 4K recording it is limited to 15 fps, so most people will probably stick to recording at 1080p30 or 1080p60, and possibly at 720p120 for slow motion effects. Moreover, the sensor used is only 4MP (2688×1520), so 4K resolution is only possible by using extrapolation.

You can’t create resolution by interpolation. It is not possible to create information from nothing.

That sensor can make a 4MP image at 90FPS, but 4MP != 4K. 10MP == 4K. Like the OV10823.

The blurbs for the V3 say 1080P-FPS. So that is 1920*1080*3*70 = 435MB/s. 4K-15FPS is 4096 * 2160 * 3 * 15 = 398MB/s. So it is possible that the Allwinner V3 can do 4K-15FPS but it would need the OV10823 sensor, not the OV4689.
